Where is blower resistor located on a 95 GMC, how to install?

I just replaced my blower motor in my 95 GMC Sierra and it only setting it blows on is high. I was told that it was blower resistor. I bought a resistor and can not find out were it is at. I think it is behind the glove box but I cant see it. Do I have to remove the dash board to get to it, if so how do I do it? Thank you for any help.

there are two rods that slide down from the top. you have to turn to get them out of clip then pull up. once both are out then headlight can be removed.

Note that many problems that show up as transmission issues are actually PCM or electrical, and may be external to the transmission. Try a different PCM, and check for chafing where the cables come out of the PCM.

The transmission is on the same fuse as the MAF, O2 sensors and at least one other sensor - if an O2 shorts out, it will blow the fuse and the trans will go into limp-home mode. Be sure the trans has power and the fuse is not blown before doing anything else.

Limp mode is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

Check the wire harness clip on the transmission, passenger side by the catalytic converter. Look for any damages due to corrosion or brake in the wire leads. it's common for the clip to brake and the wire harness to loosen causing the transmission in to limp mode. Good luck and keep me posted, be glad to help you get your transmission running again soon and please rate.

Check for check ball wear on the separator plate and address it if needed. The 1-2 check ball wears out and sometimes the check ball blows through or sticks in the plate causing troubles.

Just thought I would point out a few items to think about. Good luck.

1995 GMC Sierra fan blower not working.

Have disconnected the blower motor and hooked it up to another electrical source and it does work. Checked the resistor for continuity and it seems fine. Have replaced the switch and the relay and it is still not working. Totally stumped! Any help would be greatly appreciated.

In the beginning you should check for voltage and ground.
The 50amp fuse marked AC powers the blower motor and the motor is grounded.
The high speed relay bypasses the resistor. So you should have power coming from the fuse and thru the high relay. Then the resistor for the other speeds gets power from the heat and ac control module which also controls the blend doors.
You may need a shop manual or repair book to get the diagrams.

'94 GMC C1500 --tail lamps/rear parking lamps not working

I just purchased a '94 C1500 and am trying to fix an issue with the rear tail lamps, which do not come on with the headlamps or parking lights (the license plate lamp also fails to come on). The brake lights operate fine, as do the turn signals, hazard lights, and reverse lights.

The first thought that came to mind was a blown fuse. When I checked the panel beneath the dash, I was surprised to see hardly any fuses in the block. The manual I have been using (Haynes manual #24065, Chev. & GMC pick-ups, '88-'98 all models, '99-'00 C/K Classic)) to diagnose the problem shows a picture of a panel very similar to this, so at present I'm assuming this is normal(?) This manual also mentions an 'underhood fuse relay center' which I haven't located.

Unable to locate a fuse (and considering that the other lights are working, which seem to run off the same fuse) I replaced the bulbs, and also the tail light circuit boards, which I've heard are prone to failure. The tail lamps are still not functioning.

I have not found any breaks in the wiring from the T connection at the rear of the truck up to the front. The ground also seems solid. Are there any other components which could have failed? Please help!
